By way of comparison; I think my 367Streeter runs 74/82 , and went 93 in the Eighth on that. The math says 433hp IIRC. I think it's a tad fat, but I've been running that since 2004, and still on the same plugs,lol.

Where in Texas are you? I'm in Georgetown. What did you end up with for jetting? Just curious, I'm playing with jets in mine. Right now I'm running 70/88 in a 750cfm Proform double pumper on a 410ci with a one inch spacer on an air gap. My 410 is almost part for part the Blueprint crate, but built before they started. Same heads (though ported now) crank, cam, very similar pistons and same 10.1:1 scr. Been going up on secondaries, since I added the spacer it was leaning out at WOT. Puts my AFR @ about 13.8 cruise and 12.5 WOT and running like a raped ape. Still a lean spot during transition to WOT that I need to work on, but getting there.

Yup. Its not the 'rating' that's important for the jetting, its the actual booster type and venturi sizes as well as the air bleeds, 'emulsion' holes and so forth. So start with what the carb manufacture provided since it should be ballpark if they have any clue as to what they are doing.

South Central, next to SA. That puts me about 300 miles south of you.

I haven't gotten it running yet. It runs, but I mean running. It needs exhaust, and a professional job at that. Someone in here recommended Flanagan's Muffler Shop. He is in Marble Falls. I plan on getting it there this week. I will let you know what I end up going with, but I will need you to reply again to remind me, memory ain't what it used to be. lol

I have 74/84's in there now if I remember right, and it isn't running very rich, just a tad at cruise and idle. Still in my break in period, and I havne't driven it much since I got it put together due to financial woes. Soon it will be up and running though... I'm hoping for next week. I went one step up on the bleeds, brought it into the slightly rich side. Just a tad. There is no in between I don't think, between the stock and one step up in the bleed kit.

I'm gonna pm you a number to a guy I used for my 72. If he is still doing exhaust, you should call him. He is an old drag racer , now in his 80's,and he "retires" every summer when it gets too hot. He does nice work, though, and it won't cost you $1000! I need to go see him myself if he is up to it, for my new 71 Duster.
